Does the hi power cable (from coil to distributor) has the woven metal shield? If so that could be causing a weak spark; solution: remove the shield. BTW Do you mean to say that it's 40 K miles ago that you last services the car? Is that also the time that you installed John's spark plug wires? A car like ours needs servicing each 7500/15000 Miles, however cables, cap and rotor should last longer. Since your car is subject to water in the engine bay, it also could be possible that some of the spark plugs are drowned. It's simple to check if all spark plugs fire: use an old spark plug and test all wires, while grounding the plug. If the problem is with a wire you'll find it. Welmoed.

I'm running Hervey's silicone, hi-po wires vs. stock Bougicord wires. Symptoms: Car is very hard starting/non-starting if parked in heavy rains. It seems as if the secondary ignition is grounding out to the engine block instead of the plugs. I live in a townhouse with no garage. I routinely cover the car but this isn't really enough to keep all water out of the engine bay. The problem has become slowly worse over the years and I'm about 40k from my last tune-up. Do the symptoms jive with worn ignition or am I looking at another problem? What are your thoughts about dielectric grease on the plug wires? Waste of time? Good idea? Do you just put it on the boots, or along the wire or what?
